9 Claims.

The inverition relates to phonograph mech? anism and has reference inparticular to a record playing device having automatic means forprotecting the records and the tone arm during periods of play and whichsaid means can be employed in combination with record changingapparatus.

The record playing device of the invention has been designed to fulll adenite need of dealers in records who are required to allow customers tohandle their records and'to manipulate whatever type of phonograph theyhave been ableto provide. This is costly to dealers since the recordsare often damagedy by careless customers who drop the tone arm on therecord or scratch the same by failing toproperly lift the arm followingplaying of the record, Also the needles are subject to damage and sincea high quality needle must be used vfor the best reproduction thiscreates a temptation for the customer to appropriate the needle. Thedealer is constantly checking his equipment and replacing damaged orstolen parts.

An object of the invention is to provide phonograph mechanism which willbe automatic in the playing of a record after the same-has beendeposited on the turntable vand `which will provide means for protectingboth the record and the tone arm during the playingv period.

Another object of the invention resides inthe provision of phonographmechanism having novel means for actuating the tone armfand wherein thetone arm and record are'automatically enclosed by canopy means forprotection during playing, with the tone arm likewise being protectedduring non-playing periods so that the customer or operator is onlyrequired to change records.

'Another object of the invention resides'in'the provision of phonographmechanism which will incorporate canopy means as herein described forprotection of the tone arm and records and which canopy means willvhave'certain flexibility in structural. design so that the canopy meansmay be adapted to various cabinets.

Another object resides in the provision of canopy means for phonographmechanisml which will have movement in a horizontal plane substantiallyparallelwith the vturntable for enclosing the tone arm and recordsduring playing periods and which Will be automaticallypositicned so asto protect only the tone arm during non-playing periods.

Another object of the invention resides in the provision of mechanism incombination` with canopy means for a phonograph for automaticallymanipulating the tone arm of the phonograph and which mechanism willautomaticallyv position the tone arm for playing a ten or twelve inchrecord.

Another object of the invention is to provide canopy. means includingsubstantially semi-circular sections having movement in a horizontalplane for protection of the tone arm and records and wherein thehorizontal movement of the canopy sections will be synchronized withmovement of the tonearm.

lWith these and various other objects in view, the invention may consistof certain novel features of construction and operation, as will be morefully described and particularly pointed out in the specication,drawings and claims appended hereto. f

Referring to the drawings, particularly Figures 1, 2 and 3, the presentinvention is shown as embodied in a phonograph cabinet indicated bynumeral I and which essentially consists of a base II the same providingan interior partition I2. The turntable I3 is located above partition I2and within cabinet I0, the same providing the necessary support for therecord I4. The tone arm I5 is likewise located within cabinet II)adjacent the rear of the same and as a result of the swivel post I6 thetone arm is movably supported for coaction with the record I4 wherebyplaying of the record may be effected.

- The invention provides canopy means for enclosing the turntable andrecords for protective purposes during playing period-s. Said canopy ispreferably formed of two semi-circular sections indicated by numerals I8and 2Il. The canopy sections are suitably supported for rolling movementon the cabinet partition I2, which structure will be presently describedin detail, and in addition, said canopy sections are provided withcushioning means 2| comprising rubber pads suitably xed to adjacent endsof the canopy sections which have contacting relation when the sectionsare in closed relation. In operation the canopy. sections have movementto and from an open and closed position, the said sections moving in ahorizontal plane substantially parallel with that of the turntable andin an arcuate path to an extent whereby the sections completely enclosethe turntable and tone arm during playing periods. When the phonographis at rest, that is, during periods of nonplay, the canopy sectionsassume an open position whereby the turntable and any record supportedthereon are exposed and "acces-sible to the operator with only the tonearm being protected.

. Figures 4, 5 and 6 show the constructional details of a canopysection, it being understood that the sections are identical and thatthey are operated simultaneously and to a like extent for Section I8,which has been selected for illustration in Figures 4, 5 and 6,essentially consists of a semi-circular wall portion 22 and whichextends in a vertical direction, the height of which is optional,depending on the type of record changing apparatus employed. Saidvertical wall portion of the canopy section is provided with a topportion 23 which extends inwardly for a short distance and terminates inthe upstanding flange 24 of circular extent. Each canopy section issuitably secured'to laplatesubstantially wedge shaped, identified as 25for section I8, and 26 for section 20, the apex of the wedge having anopening 21 with the outer circular edge of each plate having theupstanding yflange 28 by means of which the plate is secured to thevertical wall 22 of the section. The plates 25 and 26 terminate short oftheir respective ends of the canopy section whereby space is providedfor the rollers 29. The rollers contact the cabinet partition I2 and asa result each section is supported for rolling movement. The front edgeof each canopy section adjacent front roller 29 is provided withresilient material 2I, as previously indicated, and which may comprisesponge rubber or the like for the purpose of closing the gap between thesections when in closed relation. Also as a result of the rubber coverededge the sections close in a substantially noiseless manner and damageto the operators fingers or the like is avoided in case the canopysections should close` upon them.

The cover for the cabinet may be associated with the canopy sections I8and 20, as shown in Figures 1, 2 and. 3. The cover essentially comprisesmember 30 having a vertically projecting ledge 3I of semi-circularcontour and which may be stepped as clearly shown in Figures 2 and 3.The periphery of portion 3| interts with the upstanding flange 24 of thesections, the said intertting relation providing guiding means for thesections and the same further effectively preventing access to theinterior of the cabinet such as would result in interference with thetone arm or record. For spotting the records on the turntable when thecanopy sections are open the cover 30 may be provided with a centralwindow such as 32.

The central spindle or shaft for the turntable I3 is best shown inFigures 8 and l0. Thesaid shaft, designated by numeral 33, extendsthrough the turntable by means of the reduced portion 34 which is usedfor spotting and retaining the records on the turntable. The shaft issuitably xed to the undersurface of the turntable by means of the collar35 and said shaft extends through the partition I2 of the cabinet todepend below said partition and which depending portion is suitablyjournalled by bearing 36 supporting the ball bearing race 31 Yand whichbearing is suitably secured to the undersurface of partition I2. yAportion of shaft 33 extends below bearing 36 and the gear Wheel 38 isfixedly secured to said depending portion by the set screw 39. It Willbe understood that the turntable shaft 33 and thus the turntable I3 willbe rotated by an electric motor, not shown, and which may be employed ina manner to drive shaft 33 directly or to drive the turntable direct asin the case of a rim drive motor where the drive is preferably appliedto the inside peripheral edge of the turntable.

The turntable shaft and more particularly the gear 38 constitutes thedriving instrumentality for oscillating the canopy sections, a preferredembodiment of mechanism for effecting said operation of the canopysections being shown in Figures 8, 9 and 10. The stud shaft 4l] issuitably secured in depending relation to cabinet partition I2 as bymeans of the screw 4I. Said stud shaft 40 provides journalling means forthe lever 42 of right angle formation and which provides arms 43 and 44.The shaft 46 also journals a gear wheel 45 and the control disc 46 isretained in journalling relation on shaft 40 by screw 41. A number ofcollars 48 are located between the gear wheel 45 and the control disc43, thus maintaining the parts in desired separated relation, andbymeans of the studs 49 extending through the collars the parts areconnected together in fixed relation.

The arm 43 of lever 42 carries at its extremity the stud shaft 50' whichprovides journalling means for the pinion 5I and the friction wheel 52,the same being retained by screw 53. The pinon-5l is adapted to havemeshing engage-.-

1 5 ment with gear wheel. and although the lever 42 may be oscillated,it will be. understood that meshing relation between the pinion and thegear is nevertheless maintained. The arm 44 of lever 42 carries at itsextremity the armature 54 which is adapted to be attracted by magnet 5,the said magnetbeing supported in depending relation from the.undersurface of partition I2 by means of bracket 56. rIjhe armature isin contact withsaid magnet, as shown in Figure 9, which has producedoscillation of lever 42 in a counterclockwise direction with the resultthat the friction wheel 52 is caused to engage the gear wheel 38. Gearwheel 38 has rotation with turntable I3 and thus power is suppliedthrough friction wheel 52 and pinion 5I togear 45 which causes rotationof control disc 4B, xedly secured thereto. When magnet 55 is de-energized the spring collar 51 exerts tension on lever 42 to produceclockwise rotation o f the lever to an extent which will bring arm 44into contact with stop 58. This will disconnect the drive between thefriction wheel 52 and gear 38 and the parts are retained in thisposition by spring 51 and stop 58 until the magnet is again energized.

lli'he control disc 46 is provided with two notches displaced 180degrees and which areidentii'led by numerals 68 and 6I. The switchmember 6 2 is adapted to coact with said notches, said switch memberbeing suitably supported from the cabinet partition I2 by means of thebracket 63. The bracket also supports the switch contacts-64 and whichhave associated relation with the member 62. nso that the circuit tomagnet 55 is` open and the magnet is de-energized. When the operatorpushes the start button he initially energizes magnet 55 and as a resultof rotation of control disc 46 member 62 is displaced by movement ofnotch 68 so that switch contacts 64 are closed and the circuit to magnet55 is held closed until notch 6I coacts with the end of member 82. Thiseffects opening of switchV contact 6,4,v whereupon magnet 55 isde-energized and lever 42 is'rotated by spring51 so as to disconnectdriving relation between frictionwheel 52 and the turntable ,gear 3 8).Operation of the parts as above .described is such as to result inrotation of control discl46 for av half revolution. When the controldisc'is rotated a half revolution to start the playing of a:.record thecanopy sectionsare caused to close and in a similar manner the sectionsare caused to openfby the n ext half revolution of the control discwhich locates the parts in their initial position with the tone arm atrest. j

Mechanism for producing oscillating movement, of the canopy sectionsincludesthe drive Viod 6 5 which is pivotally secured to disc 46 .bymeans of the threadedstud 66, thecollar B1 being rinterposed betweenvthe `parts to maintain them in proper separated relation. The other endof drive Vrod 65 is pivotally secured to the carriage .6.8. APivotallconnection of drive rod 85l tothe .carriage is effected by stud shaft 55with screw -1-(l retaining the parts to the shaft. rEhe car- Yringe '68-is supported for movement on the rods 1I, the said rods being'retainedin parallelrela, :tion with the partition I2 ,by ,the depending brackets12 and 13. The levers 14 and 15 are pivotally secured at one end to thecarriage 68, ,the said studd :extending through and above .the carriagefor this purpose. At their-other end each lever is pivotally secured toa plate comprising an'element of the-canopy sections." Ac- 45.,y asshown in Figure 9.I i

The switch contacts 64 are normally open,

cordingly. lever 14. kis -pivotal-ly secured '.bystud 161to .plate 25,whereas, lever 15 securedfby means ofstud 11 to plate 26. The'studs havelocation within arcuate slots 18 and 19t and which have an arcuatelength sufcient to allow the canopy sections to assume a complete closedand open position. Levers 14 and 15 pass through bracket 13 wherebysaidlevers :are supported intermediate their length. .The plates25 and 26 are mov-ably associated with-each other and with respect to stud ,3 3vas an axis sincefsaid stud passes through the opening 21 in the apex ofeach plate. The plates therefore have movement about the said turntableshaft as a vertical axis4 with the outer periphery of the plates'andalso `each canopy section being supported for rolling movement by thewheels 29.V Each half revolution of the control disc 45 will thusactuate driverod 65 from one dead center position. to its other dead,center position, effecting full reciprocation of the carriage 68 andactuation of levers 14 and 15 Vto cause oscillating movement of plates25 and 26 and their associated ,canopy sections I8 `and 2U.

The oscillating and elevating means for the tonefarm I5 is best shown inFigures 10, l1 and 12. The tone arm is supported on the swivel post I6by means of bracket 88 secured at its upper extremity to the tone armand havingpivotalconnection on a horizontal axis at 8| with the. swivelpost I6. Said post is supported by the cabinet partition I2 in a mannerpermitting rotation of the swivel post on a vertical axis. The rod 82extends vertically through the swivel post having the arm 83 yiixedlysecured to the end projecting above said post and whicharm is locateddirectly below and in substantial alignment with tone arm I5. The outerend of the arm 83 is reduced in width as at 84 so as to project througha slot in bracket 85 xed to tone arm I5 and depending downwardly of thetone arm. When rod 82 is rotated said movement is imparted to arm 83 andthrough bracket 85 to the tone arm. When rod 82 is elevated armA 83 islikewise elevated, the said movement being imparted to tone arm I5 bymeans of the threaded stud 86 retained by the arm 83. Said stud isvertically adjustable and is held in desired position by the 'coilspring 81.

The section of rod 82 depending below swivel post I6and partition I2 isprovided with a pair of levers 98 and 9i. Lever 98 is fixed to collar 92on the rod 82 and which collar is suitably pinned or otherwise securedto said rod so as to. rotate therewith. AThe outer extremity of lever 88'carries the pin 93 and which is instrumental in effecting oscillatingmovement of the tone arm from a 'position of rest to its initialstartingposition on the record. The lever 8i is fixed to collar 94' onrod 82 and which has movementindependently of the rod so that rotationof the rod or elevation ofthe same is not imparted'to lever 9i. Thecollar 94 is supported in proper vertical position on rod 82 by means ofthe triangular plate 95. Said plate comprises partof the supportingstructure located on the underside of partition I2 and which includesthe main supporting plate 96 resiliently supported by the rubbercushioned supports 61 from the partition member I2. The screws 98 areemployed to retain the cushioned supports in place.

The plate 96 provides a supportfor the depending studs 186 and IOI, thesame being secured to the plate soI as to depend from the underside ofthe same by screws IGZ. These studs support the triangular Vplate whichis 7 located intermediate the length of the studs, and they Valsosupport at their lower extremity a second plate I 03, the same beingsecured to stud by the screw |04. The screw |05 not only retains plate|03 in place but also provides means for pivotally supporting the arm|06. At this pivotally supported end of arm|06 the same carries anelevating plate |01 which has associated relation with the rod 82 toeffect elevating movement of the rod as a result of movement of arm |06in a certain direction.

When the arm has rotated to the position shown inFigure ll, the rod 82is released and the same descends to an extent where arm 83 rests on topofthe swivel post I6. The opposite end of arm |06 is slotted, as bestshown in Figure l1, the slot being indicated by numeral |08. The slotreceives the stud shaft 69 depending from and carried by the carriage 68so that reciprocating movement of the carriage produces oscillation ofarm |06 about screw |05 as an axis. Figure l1' illustrates the twoextreme positions of arm |06, the position as shown in the figure beingthat position when carriage 68 is located forwardly of the supportingrod 1| and adjacent to the front bracket 13. The canopy sections areclosed when the carriage 68 is so located and the turntable is rotatingfor playing the record supported thereon. With arm |06 so positioned,the elevating plate |01 is out of contact with rod 82 so that the rodassumes its lowered position, W- ering arm 83 to effect disengagement ofthe adjusting'screw 86 with respect to the tone arm. The tone arm isthus free to move over the record as required during playing of thesame.

The lever 9| is formed with a slot I0 and which is provided forreceiving the pin 93. A member is suitably secured to the top surface oflever 9|, having overlying vrelation with the slot ||0, and which memberhas an extension ||2 formed to provide an upturned lip which normallyoverlies pin 93 so as to allow the pin to be gradually forced undermember lil and into slot H0, this action taking place when the pin 93has been elevated by the elevating plate |01. Member is also formed witha detent ||3 adapted to receive the pointed end of the pin when the sameis so elevated and which effects an interlocking between the pin 93 andthe arm 9| to which member is secured. A second member ||4 is also xedlysecured to lever 9|, the said member providing the depending flange |5.A control member l I6 is pivoted to the underside of lever 9| by meansof the screw l1, said control member providing a depending part ||8which carries the threaded screw locked in adjusted position on part |I8bythe nut |2|. The coil spring |22, Figure 11, is secured at itsrespective ends to part ||8 and depending ange ||5 and said springfunctions to r-esiliently bias the control member ||6 in acounterclockwise direction on lever 9|. As a result of the tensionapplied by the coil spring the adjusting screw |20 is maintained incontact with said flange I I5, In eiect the control member ||6 comprisesa pivoted extension of lever 9| and which may be adjustably positionedwith respect to said lever by adjusting screw |20. The

Vflat spring member |23, suitably supported by the 8 so that the recordand tone arm are protected from interference by the operator. The lever9| is shown in said gure in the position it assumes when the playing ofa record is finished. It will be observed that pin 93 is in spacedrelation with respect to arm |06 which is necessary in order to allowsaid arm to rotate counterclockwise the necessary distance to cause theelevating plate to engage the lower depending end of rod 82, elevatingthe rod and effecting lifting of the tone arm. As a result ofreciprocating movement of carriage 68 in a rearward direction to causeopening of the canopy sections, arm |06 will be rotated in saidcounterclockwise direction and imf mediately following elevationV of rod82 the arm will contact pin 93 to cause counterclockwise rotation oflever 90, rod 82, arm 83, and the tone arm, which is now in elevatedposition, havingI been lifted from the record by the Ielevating actionof said rod 82. This counterclockwise rotation of the assembly is theresult of pin 93 moving under the lip ||2 and eventually into the detentH3. The lever 9| is releasably locked to the pin 93 and oscillatingmovement of arm |06 is thereupon transmitted to the lever. It will beunderstood that the counterclockwise rotation of lever 9| takes placeagainst the tension of the flat spring |23, the said rotation locatingthe tone arm in a position of rest and also locating lever 9| in aposition whereby return of the lever, that is, clockwise rotation, maytake place for the purpose of returning the tone arm for playing arecord. The locating of the tone arm is automatic, the control member H6in combination with other elements functioning to determine the initiallocation of the tone arm for playing either a ten or twelve inch record.This mechanism which operates in conjunction with control member ||6will now be described.

Referring to Figure '1, it will be observed that when the canopy is openor in non-playing position a rubber roller |24 is in contact with theexterior of the canopy sections. The roller |24 is rotatably secured byscrew |25 to arm |26 which is pivoted at |21, Figure14. The said stud|21 extends through the arm and throughthe spacing collar |28 and thenthrough partitionV |2 to depend below the same. The stud is retained bynut |29. The end of arm |26 opposite roller |25 vcarries the dependingpin |30 and in certain positions of arm |26 the pin |30 is located inthe path of the control lmember ||6, whereas, in other positions of arm|26 the said pin is not in the path of control member ||6. The arm |26adjacent the roller is formed with a depending flange |3|, the sameproviding a stop having coaction with the adjusting screw |32 carried`by the bracket |33, Figure 13. The screw |32 is provided with a knurledend v|34 to facilitate adjustment of the screw and the same is locked inadjusted position by nut |35. The coil spring |36 has connection withthe arm |26 adjacent pin |30 so as to yieldingly bias the arm in aclockwise direction, Figure 13, retaining roller |24 up against thecanopy sections when the sections are closed. Upon opening of the canopysections for playing a record supported by the turntable I3, Figure 14,the roller |24 will be yieldingly biased in a direction to contact theedge of said record as shown, provided said record is a twelve inchrecord. As a result the positioning of arm |26 is such as to locate pin|30 in the path of the control member ||6. In the event a ten inchrecord is supported by the turntable, the roller will not engage theedge of the 'same land thus the arm |26'will be so positionedby spring|36 as to locate pin |30 out of the' path ofcontrol member H6. Theseveral positions `of control member H6, arm |26 and associated partsare illustrated in Figure 13.

y lOperation of the phonograph mechanism of the invention for playing atwelve inch record will now be described. Since magnet 55 is include din the control circuit which also includes the motor for rotating theturntable |3, it will be understood that energization of the turntablemotor will energize said magnet, whereupon lever 42 is caused torotatefriction wheel 52 into driving relation with-gear wheel 38. Rotation ofthe turntable causes rotation of said gear wheel and through the drivingconnections the control disc 46 is rotated to effect reciprocatingmovement of carriage 68 and oscillating movement of the canopy sectionsI8 andv 201m a direction to cause the canopy sections to close. In otherwords, withl the canopy sections in open position they are locatedbetween the turntable and the tone arm, providing access to theturntable but preventing access to the tone arm so that protection isprovided for the tone arm during nonplaying periods. Immediately uponthe start of a playing period the canopy sections are caused to closeand as a result of this closing action protection is provided for therecord and the tone arm during playing periods.

l Opening action of the canopy sections will free roller |24 which isyieldingly biased in a direction to move into contact with the recordsupported by the turntable. For a twelve inch record the roller |29 willbe caused to contact the edge of the same and thus arm |26 willfbe sopositioned as tolocate pin |30 in the path of the control member H6.Automatically with opening of the canopy sections the arm |06 isactuated in a direction to move away from pin 93 but the pin isretainedin contact therewith by tension applied to lever 9| by the at spring|23. This action effects a returning movement of the tone arm inelevated position toward the turntable and it is only necessary topredetermine the extent of movement of lever 9| in a returning directionin order to locate the tone arm for a ten or twelve inch record. Thisis` accomplished by pin |30 which has been located in the path ofcontrol member H6. The control member contacts the pin and lever 9|continues tomove under the tension of flat spring |23 until arm |26 hasrotated counterclockwise to an extent to cause flange |3| to contactadiusting screw |32. By adjustment of said screw |32 preoise loont-ienci the tone arm for a twelve record can be effected. After this hastaken place lever 9| is held against further rotation and rod 82 isstill in elevated position, holding the tone arm out of contact with therecord. Continued movement of arm |06 eventually releases rod E2 and thesame is lowered to deposit the tone arm on the record.

Upon the lowering of rod 32 pin 93 is correspondingly lowered so thatthe interlocking relation which the pin 93 has in elevated positionwith4 lever. 9| is discontinued and thus the 4rod 82 and tone arm arefree to move over the record during playing of the same.

When a ten inch record is placed on the turntable for playing,l themechanism for closing the canopy sections operates as previouslydescribed. Theroller |21?, is accordingly released and arm |26oscillates under tension of spring |36 to the full extent of .itsmovement in a clockwise direction since roller |24 cannot contact the:edge of aten inch record. Control member |I6- and lever9| are thus freeto move the full extentof their movement since pin is not located in thepath of control member H6. Said member continues to move until' itcontacts stop |38. This locates rod 8-2 in a position where tone arm I5is properly located over a ten inch record and upon lowering of rodu 82the tone-arm is deposited on the record for playing the same. Foradjusting the tone arm-for a ten inchl record' the adjusting screw |20is employed since adjustment of this screw will vary the position ofcontrol member H6 on the lever 9|.

Referring again to Figure 11, lever 9| remains stationary duringtheplaying of a record in whatever position it may be located, dependingon whether a ten or twelve inch record is being played. ,Howeven lever90 is shownv in Figure l1 in theV position it assumesv when the playingof a record is. nished and the parts areabout to be returned toinitialposition. It will be observed that pin 93 has moved a distance fromdetent I3 which is the result of movement of the tone arm over therecord during playing of the same. When the playing period is nishedlever 90.y is so located that the rear extension |40 effects closing ofareturn switch whereby the mechanism is actuated to return the tone armand associated parts to their initial position. TheV rear extension |40carries an adjustable set'screw |4| which is adapted to contact theactuating member -of a pair of switch contacts |42, the said switchcontacts being included in theV electric circuit with the magnet I55andswtch contacts' Gt.v Therefore, with the closing of switch contacts|42, the magnet 55 will be again energized to attract armature54and-oscillate lever 42 in a counterclockwise direction to therebycause friction wheel 52 to engage the gear wheel Y38. The control disc46 is thus rotated and actuation 0f switch member 62 will close thecontacts 64, maintaining the magnet 55 energized notwithstanding thatcontacts |42 open uponreturn movement ofthe lever 90. Rotation ofthe-control disc foria half revolution will produce rearward movement ofthecarriage `68 and opening of the canopy seictions |8 and 20.Simultaneously withrearward movement of carriage 68 the arm |06 will beoscillated in a counter-clockwise direction, Figure 11, to locate thepin 93 under detent H3 and to also elevate rod 82 to lift the tone armfrom the record. Asarm 06 continues to rotate inr a counter-clockwisedirection the tonev arm is maintained elevated and returned to itsposition of rest.

Operation of the various parts as above described is controlled by thehalf revolution of the control disc 46 and when carriage 68 has' beenlocated in its extreme rearward position the notch 60 will align withswitch member 62,'allowing said switch member to drop into the notch,thereby opening the switch contacts 64 and de-energizing magnet 55. Withthe de-energization of magnet 55 the parts come to rest and furtheroperation to cause playing of the record can only be started by theoperator by pushing the set button to again energize the magnet 55. Theinvention is not to be limited to or Aby details of construction of theparticular embodiment thereof illustrated by the drawings as variousother forms of they device willk of course be apparent to those skilledin the art without departing from the spirit of the invention or thescope of the claims.
